Long. 4, lat 1-50 mm. 



Hab. Karachi (E. R. Shopland and F. W. Townsend). 



A beautifully chased little species ; allied to certain 

 Odostomice with decussated sculpture, and I follow Tryon 

 in including such under the subgeneric — or generic — 

 name of Miralda. It is a semicrystalline little shell, 

 white, alternately sculptured with many longitudinal 

 ribs, crossed by prominent keels, three in the upper 

 whorls, four in the lowest. The interstices are quadrate, 

 and deep. Below the lowest keel on the last whorl, 

 the base is delicately spirally striate. The mouth is 

 oblong, outer lip simple. The columella is once plaited 

 but this is not very conspicuous. Three or four specimens.

 interstices.)

Hab. Persian Gulf, off anchor, Bunder- Abbas. 

 An exceedingly delicate, glassy nine or ten-whorled 

 Turbonilla, with very impressed sutures, and tumid 

 whorls, the longitudinal ribs being somewhat flexuose. 

 Mouth and outer lip simple, columella straight. Judging 

 from the figure, it comes near T. acuticostata Jeffreys, from 

 the Mediterranean, but a more delicate species, of about the 

 same size. The longitudinal ribs of the last whorl, though 

 terminated just above the base, which is smooth, do not 

 seem to have the spiral line at the point of termination, 

 as in acuticostata. Three examples. 

 {basilicus^ kingly.)
